So I recently bought a new honor magic 5 pro. My last phone the Huawei p20 pro was around 5 years old and started to show significantly less battery life. So I want to use this phone again for 5 years. But now I wonder should I keep the battery around 50% (65-35) and charge twice as often or should I 80-20 and charge once every two days? Is there any science that proves one is better than the other? Thank you for your information and sources.
80-20, but don’t be too strict about it either.
65-35 doesn’t make sense. Yes the battery is at its most stable around 50%, but then you charge it too often and that’s not great either, because it goes through heat cycles rather than charge cycles.
Also batteries degrade by themselves anyway, so it really depends on the quality of the battery itself how long it will last. Inconveniencing yourself too much won’t give it much extra life.
Just never discharge fully, don’t charge fully with exceptions, and charge slowly and you’re good.
